alt Hacker NewsEconomic behavior is inherently game theoretic - agents take various actions and get some positive/negative reward as a result. Whether an agent's reward is positive or negative and of what magnitude, depends on the strategies employed by all agents. If some agents adopt new strategies, the reward calculus for everyone involved can completely change [1].
Over the past few centuries, countless new economic structures and strategies have been discovered and practiced. The rewards for the same action today and in the past can be completely different due to this.
So to me, if someone claimed more than a few decades ago that certain economic strategies and structures are good or bad, its simply not worth listening to them, unless someone reconfirms that the old finding still holds with the latest range of strategies. In that case, the credit and citation goes to that new someone, not the ghosts of the past.

As you point out, it is all game theory.
But things that arrange for the game to be more beneficial to everyone, that align our interests more, deserve to be called "good", regardless of their inability to universally do so.
The latter would be an impossible bar for anything.
Where I find things frustrating, is when someone thinks because something is "good", it somehow becomes "enough". (Think, capitalized versions of different economic schools of thought.)
